SD Cards do have a write protect switch. Does anyone know if that's enforced on the card itself?
- anonymousiam 3y agoIt's not enforced by the card. It's just a plastic tab that slides so as to tell the reader that the card should not be written. There is nothing to stop a malicious reader from writing to a write-protected card.
- IAmLiterallyAB 3y agoWow really? That's annoying. Why go to all the trouble to add the switch if they won't implement it correctly
- AussieWog93 3y agoBecause engineering consumer media to be robust to a Stuxnet-level attack vector is ridiculous? The switch as-is prevents the file system from becoming corrupt when you don't "safely remove" the device, and that's plenty enough for the average photographer.
- JohnFen 3y agoI think the purpose of the switch is the same as the write-protect notches on old floppy disks: it's not really a security measure, it's meant to prevent the owner from accidentally formatting/erasing/overwriting things.
- userbinator 3y agoOr to go even further, the write-protect tabs on cassette tapes.
- calamari4065 3y agoNo, it is electrically connected, but only to the connector. That's why one of the edge contacts is split in two. It's still up to the host to enforce.
